2 Claims. (Cl. 284-48) -too much twisting and turningorgreat manualforce in order to make a good fluid-tight connection.

The invention herein disclosed is believed to eliminate all theunpleasantness and awkwardness of making the old type of hose connectionto hydrants and/or another length of hose; this invention beingespecially adaptable to high pressure lines and to fluid conductors thatare in inconvenient places or so situated that the usual screw typecoupling cannot be easily manipulated to make a good fluid-tightconnection.

which is economical to make and manufacture.

1 Another object is to provide a coupling with simple push and shorttwist means ofoperation in order to join the parts thereoftogether andtomake connection between a pairof pipes,

tubes, or hoses, and likewise a simple twist and push only beingrequired to uncouple the things connected.

Other objects, advantages and features of my invention will appear fromthe accompanying drawings, the subjoined detailed description, the

claims.

preamble of these specifications and the appended In the drawings:

Fig. 1 is a longitudinal axial sectional view of valve in Fig. 1,

Fig. 3is a transverse sectional view taken substantially along the line3--3 of Fig. 2,

Fig. 4'is an elevational view of one end of the device, and Fig. 5 is anelevational view of one side of the device, and showing the twocomplementary parts view at one end of 2 separated, thus presenting aclosed valveposition in the left hand portion of the parts.

The coupling or/and valve connector device consists of the two principalparts I and 2, the outer ends of which are adapted to receive a hose,pipe, end of a spout or hydrant, or any means through which fluid ispassed, the broad idea being to connect the ends of two fluid conductorsquickly and easily in a hermetically sealed state until purposelydisconnected.

The part 2 comprises an elongated element having a central bore 3 andthe integral and nutlikegrip means 4, this grip means providing a stopfor the hose 5. The hose is made fluid tight with the annular ribbedextension 6 by the metal or plastic band I. Extending from the otherside of the grip, there is an annular tube-like projection 8 whichmerges into a reduced annular tube-like projection 9, the very end ofthe projection 9 being a plain annular smooth end as indicated at I 0.This part of the valve coupling might be "called a teat-like element,the insert member, or male member, in that it is inserted into the otherpart I and is provided with integral cleats or dog-like projections Hand I2 which make a locking connection with thepart l in a manner to beexplained later.

The part I includes the thre annular casings l3, l4 and I 5, the casingl3 being threaded at 16 to engage the threads I"! of the casing 14, asshown. The casing l3, at its outer end, is provided with the taperedthreads I8 which are designedto make permanent or semi-permanentfluid-tight connection with pipe or hose, or this end may be providedwith a threaded female member to make fluid-tight connection with aspout orhose bib extending from a building or the like. The casing 13has the fiuid passage bore 49 which opens into an enlarged annular 40chamber", the outer surface of this portion of the casing being providedwith the threads 2| to receive the threads 22 of the casing l4.

The casing 14 has its end shaped as shown to provide the guide annularedge 23 which snugly but slidably receives the extension 9 of the part2.

The casing I4 has an annular recessed portion to f The internal wall ofcasing I4 is provided. with an annular recessed portion to accommodatethe 'metal or plastic sleeve or washer 25 which provides a snug trackfor a shiftable member 26 to be better explained later.

The other casing l5, of the part I, has inwardly -extending fingers 21and 28. these fingers are looking members, but they cooperate with-thethe coupling unit. I

It is,v of; course, understood-that various changes,

annular shoulder 29 of the casing 84 in positioning and limiting thecoiled compression spring 39. The casing I4 has a pair of spaced apartprojections 3! and 32, each of which has a short upstanding lip 33 whichprovide shoulder stops for the lock ring 34 that holds the casing 15 intelescoping relation with the casing M, as shown. It should now beapparent, thatthe; fingers 2.11, and 28 canslip between the projections3land 32 when it is desired to release the casing l from the casing M orlock the casings together.

Within the chamber 20, there is a helicalspring,

, thewend adapted to enter the receiver consisting spring and it has anannular flange-likeportion including a plurality of finger-likeprojections 38, the, outer surfaces of which act as guides for the valvemember within the bore of the chamber 2.0 and the spaces therebetweentoprovide passages tor freefluid flow from one side of the valve member tothe other side thereof' Integral with the valve member islthecylindrical extended. portion, 2.6: which has a cavity 39 that-is openat the end it thereof; this cavity, however, having also open connectionwith a plurality of holes 40, these holes ii! connecting the cavity39with the surrounding chamber 2 when the valve member 26, is forcedtowardthe helical spring 34;

There is an annular recessed portion 41- on the valve member whichpositions an O. ring which may be; rubber. or neoprene or made. of anyother suitable type and kind of material. These 0. rings form excellentsealing rings for the valve part i by giving part 2 a slight twist afterfirst pressing the casing 15, against its spring 3il-so as women thedoor or spot M this allows/the, doglikeprojections ii and H to passthrough the gap Hi when in register therewith.
